Abstract (en)

An electromagnetic induction heating apparatus 1 in which an object to be heated such as a half-finished light alloy wheel can be heated efficiently to have a predetermined temperature in a short time includes a rotating body 2 with a plurality of magnets 21 arranged such that the same pole is positioned on the side of an object to be heated 8 and a rotation driving motor 3 for rotating the rotating body 2, in which the object to be heated 8 is heated by an induced current generated when the rotating body 2 is rotated. By controlling the distance D between the magnets 21 of the rotating body 2 and the object to be heated 8 with a moving motor 6, a light alloy wheel or the like, which has a high thermal expansion coefficient, can be well-heated efficiently.
